Unveiling the Secret Behind Building a City-Scale Dynamic Digital Twin of Hong Kong

On 1 June 2024, Kenneth Sung — Executive Director of Jadason Group, Managing Director of Metason, and lead architect of Hong Kong’s city-scale dynamic digital twin — delivered a special feature talk hosted by the Hong Kong Geospatial Lab.

Titled “Unveiling the Secret Behind Building a City-Scale Dynamic Digital Twin of Hong Kong,” the session shared practical insights into building a city-scale dynamic digital twin, including:

• Data management: How to efficiently manage massive geospatial datasets for a true city-scale digital twin using OpenUSD
• Design & architecture: Design principles and architectural choices that keep the platform dynamic and practical for real-world applications
• Development process: A streamlined approach for delivering robust, AI-powered tools within weeks
• Functionality & interactivity: Strategies to enrich the digital twin, such as integrating live traffic data from the Transport Department

Together, these themes outline how Metason turns advanced spatial data and AI into a living digital twin of Hong Kong — supporting smarter planning, visualisation, and city operations.
